I don't mean this in an unpleasant way. I just find that sometimes when I meet people I think "you look like you are a deeply religious christian" and generally I am right, they do turn out to be. I don't think it works on less committed christians. Is this like having gaydar? Does anyone else have this experience? What is it I see in their appearance that makes me think this? Am I just kidding myself about this in some way?
